SPECIFICATION forming part of Letters Patent No. 274,955, dated April 3,1883. Application filed December '7, 1882. (No model.)

To all whom rt may concern Be it known that I, RUFUS S. MATTESON, of thecity and county of Providence, and State of Rhode Island, have inventedcertain new and useful Improvements in Machines i'orMaking Chains; and Ido hereby declare that the ibllowing specification, taken in connectionwith the accompanying drawings, forming a part of the same, is a full,clear, and exact description thereof.

' My invention consists in a machine for making that variety ofornamental chains com posed of rings or rollers'which are arranged inrows and secured to each other by pins or staples passing transverselythrough the same.

As a whole, the machine comprehends an organization of parts or elementswhich act automatically; audit consists of mechanism for feeding therings in rows to aroulette receiver or receivers, mechanism for rotatingthe said receiver or receivers step-by-step, mechanism for feedingthematerial lrom which the fastening pins or staples are made, mechanismfor forming said pins or staples from said material, mechanism forpassing the fastening-pins or staples into the rings, and meohanism t'orclinching or securing theends ot' the pins or staples to complete thechain.- As far as I am aware, such a machine, as a whole, is new, as arealso combinations of certain of its elements,which will behereinafterdescribed,and

pointed out in the claims.

Referring tothe drawings, Figure l represents in front elevation amachine embodying my improvements. Fig. 2 shows a side elevation of thesame. Figs-3, 10, and 11 represent certain details of construction, thelast two figures being enlarged. Fig. 4 represents a plan of the machinewith the top portion removed. Fig. 5 shows a central vertical section ofa portion of the machine. Fig. G-represents in perspective certain formsof fastening-pins on an enlarged scale. Figs. 7 and 8 show steps in theformation of the chain. Fig. 9 represents in perspective and on anenlarged scale a portion of a completed chain.

The chain which the machine shown in the drawings is organized to makeconsists of six each other by two series of transversefastening-pins,which are inserted into the rows from opposite sides ofthe chain, and have enlarged heads, which are perforated and bent atright angles to their shanks. The points of the pins of one series passthrough the perforations in the heads of the pins of the other series,and are clinched upon the same.

As particularly shown in Fig.2,the machine is provided with two hoppers,A A, for hold: ing in mass the rings from which the chain is made. Thesehoppers are located respectively at the front and rear of the machine,and are supported upon standards a a. Extending from the hoppers aredownwardly-inclined conveyors B B, which are respectively provided withchannels I) b, for conveying the rings in rows from the hoppers to tworoulettereceivers, O C. In order to preventtherings from clogging in thehoppers, and to insure the delivery of the rings to the channels in theconveyers, arms D D are employed to stir the masses of rings, which armsare mounted on rock-shaftsff,journaled in the standards a a, vibrate invertical planes in openings in the hopper-bottoms, and are furnishedwith channels 61 d, which arein alignment respect ively with thechannels 11 b in the conveyers B B. Motion is imparted to the arms D Dby the shaft E, Figs. 1, 2, and 3, provided with an eccentric, to thestrap 6 of which rods F F are pivoted, the said rods connectingrespectively with cranks f fi, attached to the rockshaftsff.

Theperiphery of each of the roulettesO G is provided with sixcircumferential series of cups, alternated so as to form transverse rowsof three, as particularly shown in Fig. 10. The series 01' cups numbered1, 3, and 5 in the roulette O are in alignment with the channels in theconveyer B, from which channels the said series of cups receive rings asthe roulette is rotated, and the series ot'cups numbered 8, 10,

and 12 in the roulette O are in alignment with the channelsin theconveyor B and receive rings therefrom. The series of cups numbered 2,4t, and 6 in the roulette U and the series 7, 9, and 11 in the roulette0 do not receive rings from the conveyors. The former series acttos'teady the rings in the roulette O and the latter series the rings inthe roulette .0 when the roulettes have revolved sufliciently to bringthe rows of rings which they are carand bring its rings into properposition to reare attached ratchets'jj, Figs. 1, 2', 4, and 5.

"pawls K-K, Figs. 1 and 2, which are respectryinginto proper transversealignment to receive the fastening-pins as shown in Fig. 11. Between thetimes when the rings are received by the roulettes and the times whenthey are brought into proper transverse alignment to receive thefastening-pins the rings are prevented from passing out of the roulettesby curved guard-plates B B attached to the conveyers B B, respectively,and overlying the roulettes, as shown in Figs.2 and 11. The rings in theseries of cups 1 and 12 are supported transversely on the outside byflanges 1) b respectively, attached to the guard-plates, and on theinside by the points of the series of cups 2 and 11. The remaining rowsof rings are supported transversely by the points of the cups on eitherside of them.

' As shown in Fig. 1, theroulette G is mounted on a shaft, 0 to which aratchet, O is secured. As shown in Fig.2, this ratchet is engaged byapawl,'c mounted on a pivoted arm, (1 which arm is connected by a rod, 0to a lever, The engagement of a cam, 0 on the shaft E with the lever 0causes the pawl c to rotate the roulette 0 step by step veivethetastening-pins. The action of a cam, 0 on an arm, 0 which is attached tothelever 0 returns the pawl to its normal position. During the time thefastening-pins are being inserted and clinched, hereinafter to bedescribed, the roulettes are firmly held by the engagement of adetect-lever, 0'", Fig. 2, with the teeth of the ratchet An arm, (3 isattached to the detect-lever, and is engaged by the end of the lever 0so that as the pawl rises preparatory to descending tomovc the ratchetthe detent-lever is moved out of engagement with the ratchet to allowthe latter to revolve when the proper time comes.

The shaft upon which the roulette O is mounted may be geared to theshalt 0 upon which the roulette O is mounted, but as the machine isarranged revolution is imparted to the roulette U by the engagement ofthe rings in the roulette U with the unoccupied cups in the roulette 0,so that both roulettes move together stepby step.

The pins G G, which fasten the rings together, are shown in perspectivein Fig. 6. These pins are punched from two strips, H'H', of sheet metal,Fig. 5, which are drawn into the machine through guide-slots h /L',Fig.1, by two sets ofrolls, JJ JJ, which are located at the rear of themachine, as shown in Figs. 1, 2, 4, and 5, although said feed-rolls maybe placed at-the front of the machine and be arranged to push the saidstrips into and through the machine in a well-known manner. The upperand lower rolls of each set are respectively geared together, and to thelower rolls The rolls are revolved step by step by the engagement withthe ratchetsjj of spring pullively attached to two plungers, L L, movingvertically in the frame of the machine. These plungers are pivoted atthe top to two straps, e 0', Figs. 1 and 3, which surround eccentrics onthe shaft E, the said eccentrics being so timed with relation to eachother as to cause the plungers to alternate in their upward anddownward'movements. To the lower ends of the plungers are securedpunches l l, Fig. 1, which co-operate with cutting-dies Z 1 Fig. 5,respectively. Across the tops of these dies the strips, 11 H", of sheetmetal pass, as shown in Fig. 5, so that as the plungersL L descendalternately pins G G, substantially in the form shown in Fig. 6, arepunched from the strips, the points of the pins being toward each other.

Immediately below the'die l a table, M, Fig. 5, is located, the uppersurface of which is at a-distance equal to or slightly greater than thethickness of a fastening-pin from the lowersurfaceofthedie.Bysuccessiveactions of the punch l,thefastening-pinsG,lyinghorizontallyand one above the other, are passed down through the die l in a stackuntil the lowermost one-rests upon the table M, ready to be passed intothose two transverse rows of rings which have been brought intoalignment with said pin by the revolution of the roulette-carriers GO,hereinbefore explained. In order to steady the pins as they are passedinto the rings and properly to direct their points, guides areemployedone pair for the. pins G and another pair for the pins G. Thepair on m for guiding the pins G are shown at Fig. 4. These guidesoverlie a table, lll, (similar to'the table M,) and are pressed towardeach other by light springs m, Figs. 4 and 5. Between these guidesthe-pins G, one after another, are deposited, and between a similar pairof guides the pins G are deposited. A pin, G, is passed into the rings,as shown in Fig. 7, by a plunger, N, Figs. 4 and 5, which slides betweenthe guides just mentioned and between the die I and the table M. Therear end of this plunger is attached to one arm, 0. of a yoke, 0, whichyoke, by means of a connecting-piece, 0, Fig. 4, is pivoted to a lever,0 Figs. 1 and 4. This lever is pivoted to the frame of the machine, andis vibrated by a cam, 0 Fig. 1, on the shaft E, to cause the plunger Nto perform its oflice.

A pin, G, having been passed into the rings by the plunger N, thenextstep in the formation of the chain is to bend up the head of thepin,

as shown in Fig. 8. This is accomplished by the rising of a bar, P, Fig.5, which slides diagonally in the frame of the machine, and has of themachine, and has its upper end provided with rollers r, Fig. 1, whichare engaged by a cam, 6 on the shaft E. This cam reci rocates the rod Rvertically and slides the bar 1? diagonally to and from theroulettes GG. The head of the pin G having been bent upward, the roulettes arerotated a step by the mechanism already described to bring the nexttransverse row of rings held inthe roulettes into such a position as toreceive a pin, G, which is to be passed into said rings from theopposite side of the machine, and also for the i purpose of bringing theslot g in the head of the pin G, Figs. 6,. 7, and 8, into alignment withthe pin G, so that the point of the latter can pass through said slot,in readiness. to be clinched over the head of tlte pin G, as shown inFig. 9. The roulettes may, however, be revolved for this purpose beforeor during the bending of the head of the pin G, if preferred.

The pins G are punched from the strip, H, of sheet meta-l by the punchl, and die l and are passed down through said die in a stack bysuccessive actions of the punch until the lowermost pin rests upon thetable M, Fig. 5. A pin, G, is passed into the rings between the guidesin m, Fig. 4, by a plunger, N, the rear end of which is secured toauarm, 0, of the yoke 0, Figs. 4 and 5. The yoke U is moved in the properdirection to cause the .plunger N to insert a pin, G, by the action ofthe cam e on the lever 0 hereinbet'ore mentioned, which cam reciproratcsthe yoke 0 to. bring the plungers N N successively into action. Duringthe insertion ot the pin G the head of the pin G is supported by the barP. the upper nd of which is grooved, as hown in Fig. 5, in order thatthe pointof the pin G may pass sufficiently beyond the face of thepin-head G to be clinched upon it, as shown in Fig. 9. The plunger Nhaving passed a pin, G, into the rings, anti the point of said pinthrough the perforation y in the head of the pin G, so that the point ofthe former pin projects beyond the lace of the head of the latter pin,asshown in Fig. 8. the next step. is to bend up the head 'of the pin G. tThis is accomplished by the rising of the bar P, Fig. 5. This bar ismoved diagonally upward by a tooth, g, on a vibrating lever, Q which isconnected by a link, Q to a rod, it, reciprocated vertically in theframe of the machine by a earn, 6, on the shafttE,.Fig. 1, the motionsbeing similar. to those jalread v described with relation to moving thebar P. The head of the pin G having been bent upward, the roulettesrevolve another step to bring the next transverse row of ringsintoproper alignment to receive a pin G, hereafter to be inserted, and so asto .brin g the perforation g in the head of the pin G into alignmentwith the second pitt G, the point of which is to pass through saidperforation to be clinched over the head of the pin G.

The next step is the clinching of the pointofthe pin G upon the headot'the first ptn G. While the bar P supports the head of the pin G thepoint of said pin is bent upward by a forward movement of the table M,Fig. 5, the inner end of which is conceived for the purpose ofaccomplishing .the bending. Preferably there is employed,tin connectionwith the table M, a sliding bed, S, the inner end'ot' which is inadvance of the inner end of the table when both are in normal position,as shown in Fig. 5. The oflice of this bed is t0 pass under the end ofa. pin G and prevent the same from accidentally being bent downwardwhile it is being clinched. Therelative normal positions of the bed Sand table M are maintained by an elliptieal spring, at, Figs. 4 and 5.which bears upouthe rear end of the bed and upon a lug depending fromthe rear end of the table, and by a stop-pin, T, which is secured to thebed and passes through the said lug on the table M, as shown in Fig. 5.The bed and the table are maintained in are-arw ard position by aspring. m Figs. 4 and 5, which bears upon the frame of the machine andupon the lug at the rear ot'the table M. the said rearward positionbeing determined by the contact of the rear bent end of the bed S withthe bent end of a" stop, T, as shown in Fig. 5. By the engagement of atooth, (1 ,011 the vibratinglever Q with the rear end of the table M thetable and the bed S are moved forward simultaneously (the barP beingatthe same time withdrawn bythe tooth q) until the inner. end of the bedS passes under the pointof the pin G and comes in contact with theupturned head of the first pin G. The table M continues to tnoveforward, however, (the spring m being compressed,) and its concave endbends up the end of the pin G and clinches it overthe head (if the firstpin G, as shown itt Fig. 9. This operation having been performed, thelever Q swings downward and the bed S and table Mretreattotheirrearwardpositions. Although I preler to employ the bed S,yet it and the spring at may be dispensed with and the stoppin T beextended and secured to the frame of the machine. During the time thepoint of the pin G is being clinched a second pinG is being insertedbythe mechanism and in the manner hereinbefore described, the point ofsaid second pin G passing through the perioration g in the upturnedheadot'the pin G,in readiness tobe clinched the-eon. The headof thesecond pin G is next bent upward by the mechanism and in the manneralready described. The ronlettes now revolve another step to, bring thenext transverse row of rings into alignment with a second pin G, now-tobe inserted, and to bring the perforation g in the upturned head of thesecond pin. G into a position to receive the point of the second pin G.

The next step isthe clinrhiug ot' the point of the second pin G upon thehead of the first pin G while the head of the pin G is supportedby thebar P. The elinching of the point of a pin G upon the. head of a pin Gis accomplished by the table M, which has a concave end similar to thetable M. In connection with the table M there are employed a bed, S,springs m and m", a stop-pin, T and a stop, T .(shown a in Fig. 5,) allcorrespending respectively in formation and action with the bed S,springs m and m stoppin'T, and stop T, hereinbefore described. The tableM is moved forward to perform the clinching of the point of a pin G by atooth, if, on the lever Q and the table is retreated, alter havingperformed the work, by the spring m the bed S moving with said table andperforming an office similar to that described for the bedS. During thetime the point of a pin G is being clinched another pin G is beinginserted, and while the table M is. being advanced to perform its officethe bar P is. retreated by the tooth q, in readiness to be advanced tobend up and support the head of the next pin G.

The several operations hcreinbefore described are now repeated, and thechain is manufactured in a continuous length, which passes down throughthe machine into any convenient receptacle.

Although I prefer to employ hoppers for holding the rings in mass anddelivering them to the channeled conveyers, yet the hoppers may bedispensed with and the rings be fed by hand or in any preferred manner.

It will be readily understood that chains having a lesser or greaternumber of longitudinal rows of rings than that shown and described maybe made upon the machine by each otheras, for instance, a U-shaped pinor staple of round, oval, or flat wire. Such pins would be best madefrom a coil of wire fed into the machine by suitable rolls, from whichwire pieces would be successively removedby suitable cutters, the saidpieces being bent into U shape by suitable formers or devices,

and thenfed edgewise down upon one ,or both tables, M' M, or equivalentdevices. Such pin's could' be inserted into 'theriugs from one or bothsides-of the machine, and both ends of the pins would be clinched on therings by construction enables the cups to be arranged in alternatetransverse rows, as hereinbefore described, and also allows the cups tobe arranged'lnitransverse rows without alternation. The object of thislatter arrangement is to enable a chain tobe made on the machine whichis composed of longitudinal rows of rings which do not alternatetransversely, such a chain being well known. The staple form offastening-pin is best adapted to secure to each other the rows of ringsin such achain.

Although I have shown and described tworoulettes for receiving andcarrying the rings into the proper position to receive thefastening-pins, yet I am aware. that all the rings to form a chain maybe delivered by a single conveyer, having the proper number of channels,to a single rouletteO ,for instanceand the remaining roulette, eitherwith a cupped periphery, as described, or a plain periphery, be usedonly as a guard to steady the rings immediately before and at the timethe fastening-pins are being inserted and clinched. I am also aware thatthe second roulette may be entirely dispensed with, and the rings beheld and steadied in the cups of the single roulette by extending theguard-plate B down to a point a little below the plane in which thefastening-pins are inserted. All these constructions are within thespirit and scope of my invention.

What I claim, and desire to secure by Letters Patent, is-

1. In a machine for making chains, the combination of a channeledconveyer for delivering the ringsoin rows, a roulette-receiver havingits periphery provided with series of cups, as described, suitablemechanism, as described,
